Grouting guide pipe (also known as steel perforated pipe) is a small-diameter steel pipe used in tunnels and underground engineering for advanced pre-support and ground reinforcement. Grouting is injected into the pipe to improve the physical and mechanical properties of the surrounding rock and enhance stability.

Casing pipe is a rigid protective tubular product widely used in geotechnical engineering, well drilling, foundation reinforcement and tunnel construction. It is manufactured from high-quality carbon steel, The pipe is precisely processed with smooth inner and outer walls, uniform wall thickness and good sealing performance. It can effectively isolate loose soil, rock layers and groundwater, prevent hole collapse and wall damage, and protect the normal operation of internal drilling, grouting and detection equipment. Customized diameters, wall thicknesses and lengths are available to adapt to various complex geological and construction conditions.

Our water filter pipes, also known as well screen pipes, are professionally engineered for water well drilling, groundwater filtration, drainage, and sewage treatment projects. Manufactured from high-quality carbon steel, stainless steel, or galvanized steel, the pipes feature precise slot opening and uniform perforation design, which effectively blocks sand, sediment, and impurities while ensuring maximum water permeability.
Adopting advanced welding and punching technology, the filter pipe boasts high structural strength, strong pressure resistance, and excellent corrosion resistance. The threaded or welded connection design enables quick and stable installation, suitable for deep wells, shallow wells, farm irrigation, municipal drainage, and industrial water treatment systems.
We support customized specifications including pipe diameter, wall thickness, slot size, pipe length and surface treatment to meet diverse engineering and project requirements.

Sleeve valve pipe is a key component for sectional grouting technology in geotechnical engineering.
The product adopts premium raw materials, featuring high pressure resistance, good flexibility, acid and alkali resistance, and strong anti-aging ability. We supply both PVC and carbon steel sleeve valve pipes. PVC type is lightweight and anti-corrosion for regular projects; carbon steel type owns high strength and pressure resistance for heavy-duty construction
It is widely applied in foundation consolidation, tunnel water plugging, road & bridge reinforcement, slope protection, underground pipeline anti-leakage and other infrastructure projects. Custom sizes and specifications are available to meet different project requirements.

Steel flower pipe, also known as grouting perforated steel pipe, is a specially processed seamless or welded steel pipe with regular grouting holes drilled on the pipe wall. This product is widely used in geotechnical engineering, tunnel support, slope reinforcement, foundation consolidation and underground construction projects.
It effectively consolidates loose soil and broken rock masses, improves the overall stability and bearing capacity of the foundation and tunnel surrounding rock, and prevents geological problems such as collapse and settlement.
Made of high-quality carbon steel materials, our steel flower pipes feature high structural strength, strong pressure resistance, excellent toughness and corrosion resistance. All products are processed with precise cutting and hole opening, with smooth pipe walls, uniform hole spacing and no burrs. Customized specifications, hole sizes and hole layouts are available to meet different construction and geological requirements.
